Yes, you need to create a patch to add mxs framebuffer support in
U-boot. You can look at the linux kernel as a reference
(drivers/video/mxsfb.c) and port it into U-boot.

There are other i.mx processors (mx31, mx51, mx53)  that do support
framebuffer in U-boot. You can look at drivers/video/mxc_ipuv3_fb.c in
U-boot for a reference for mx51/mx53 implementation.

The LCD controller on mxs is different so that is why you will need to
create a new driver for it.
